In the fruit fly Drosophila, the functions of the three enzymes Tan, Ebony and Black are closely intertwined – among other things they are involved in neurotransmitter recycling for the visual process. RUB researchers from the Department of Biochemistr…

A team of interventional neuroradiologists and neurosurgeons at Johns Hopkins reports wide success with a new procedure to treat pseudotumor cerebri, a rare but potentially blinding condition marked by excessive pressure inside the skull, caused by a d…
